Abstract

The inherent nature of wireless communication and the added mobility factor introduces challenges in securing wireless applications. The convergence of communication and ubiquitous environment demand flexibility on various security mechanisms. The need to accommodate vertical hand-off, horizontal hand-off and resource limitations further restricts the ability to provide acceptable levels of security. We propose a number of novel solutions, which are applicable in different scenarios. They include Unified authentication mechanism with EAP framework, Group outlier based IDS, Trust-based models for MANETs and Physiological signal initiated key establishments.
We will describe in detail how low entropy physiological signals can effectively be used for secure key establishment in body area networks. Our proposed protocol has limited inbuilt-error correction mechanism. The test results of such protocol implementation with smart phones in real world environment and range of possible eHealth applications will be discussed.

Biography of Speaker

Dr. Muthukkumarasamy obtained BScEng with 1st Class Hons from University of Peradeniya, Sri Lanka and obtained PhD from Cambridge University, England. He is currently attached to School of Information and Communications Technology, Griffith University, Australia as Senior Lecturer. His early research was in developing a novel adaptive equalisation technique to decouple the processing speed from the data rate of transmission, so that it can be used in very high speed systems. His current research areas include investigation of security issues in wireless networks, sensor networks, trust management in MANETs, key establishment protocols and medical sensor networks. He has published over 80 papers in international journals and conferences and has supervised over 30 research students. He is currently leading the Network Security research Group at the Institute for Integrated and Intelligent Systems (IIIS) at Griffith University (Australia). He is a full member of the IIIS and also was a contributing member of NICTA (National ICT Australia). He is also an excellent teacher, taught range of subjects from engineering, computer science to information technology in the last 25 years and received number of best teacher awards. He is the Co-Director of Internationalisation (ICT).
